Caroline Wozniacki impersonates Serena Williams

Despite her former ranking, the 22-year-old has yet to win a Grand Slam title.

So if you can't be the best, might as well impersonate the best. That's what Wozniacki attempted to do during an exhibition match in Brazil Sunday.

Trying to get a laugh out of the crowd in attendance, Wozniacki stuffed her bra and skirt with several towels. The gesture was an obvious attempt to imitate Serena Williams, who over the years has received almost as much attention for her curvacious body as for her 15 Grand Slam victories.
